Which route is represented by the abbreviation PR?

• A. Per Rectum
• B. Per Os
• C. Intravenous
• D. Intramuscular

Answer: (A)

Understanding routes of administration abbreviations helps you quickly identify how a drug is given. PR stands for Per Rectum, the rectal route. This means the medication is administered into the rectum, typically as a suppository or rectal liquid, and it can provide local effects or systemic absorption depending on the drug and patient. It’s especially useful when someone cannot swallow or is vomiting. In contrast, Per Os means by mouth, Intravenous is delivered into a vein, and Intramuscular is injected into a muscle. So the abbreviation PR points to the rectal route.
